在Docker中运行EOS(MAC版)

在Docker中运行EOS(MAC版)

在Docker中也可以简单快速的构建EOS.IO.笔者在Mac平台下参考官方文档躺了一次河。记录如下:

安装依赖

  • Docker 版本 17.05或者更高

    testdeMBP:Docker test$ docker -v
    Docker version 18.04.0-ce, build 3d479c0

  • docker-compose version >= 1.10.0

    testdeMBP:Docker test$ docker-compose -v
    docker-compose version 1.21.2, build unknown

Docker需求

  • Docker需要至少7GB内存。(Docker -> Preferences -> Advanced -> Memory -> 7GB or above)
  • 如果下面的build失败了,确保内存的配置满足要求然后再试一次。

编译eos镜像

git clone https://github.com/EOSIO/eos.git --recursive  --depth 1
cd eos/Docker
docker build . -t eosio/eos`

这个过程需要等待一会

上面的命令默认构建master分支的最近提交。如果需要编译运行特定分支/tag,可以使用一个编译参数。例如,你想基于标签v1.0.4生成docker镜像:

docker build -t eosio/eos:v1.0.4 --build-arg branch=v1.0.4 .

默认eosio.system中的符号被设置为SYS。你可以在编译的时候通过symbol参数来覆盖它。

 docker build -t eosio/eos --build-arg symbol=<symbol> .
 

只启动nodeos docker 容器

docker run --name nodeos -p 8888:8888 -p 9876:9876 -t eosio/eos nodeosd.sh -e arg1 arg2

遇到如下错误:

zexudeMBP:Docker zexu$ docker-machine env default
Error checking TLS connection: Host is not running

解决方法

zexudeMBP:Docker zexu$ docker-machine restart default
Restarting "default"...
Starting "default"...
(default) Check network to re-create if needed...
(default) Waiting for an IP... 
Machine "default" was started.

Restarted machines may have new IP addresses. You may need to re-run the `docker-machine env` command.

zexudeMBP:Docker zexu$ docker-machine env
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/Users/zexu/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
# Run this command to configure your shell: 
# eval $(docker-machine env)
zexudeMBP:Docker zexu$ eval $(docker-machine env)
zexudeMBP:Docker zexu$

获取链信息

首先获取docker中http service的IP地址:

zexudeMBP:Docker zexu$ docker-machine ls
NAME      ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER        ERRORS
default   *        virtualbox   Running   tcp://192.168.99.100:2376           v18.03.1-ce   
zexudeMBP:Docker zexu$ docker-machine ip default
192.168.99.100

调用HTTP接口:

curl http://192.168.99.100:8888/v1/chain/get_info

得到如下信息:

{"server_version":"c9b7a247","chain_id":"cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f","head_block_num":2866,"last_irreversible_block_num":2865,"last_irreversible_block_id":"00000b315494325c32f9e930957f776e3819d4eacdc9d28f8fc6df7149318891","head_block_id":"00000b32b4ea4d06db5c78006c34be993deb952de142e3a186df5ab8312d6116","head_block_time":"2018-06-20T08:06:49.000","head_block_producer":"eosio","virtual_block_cpu_limit":3506516,"virtual_block_net_limit":18419703,"block_cpu_limit":199900,"block_net_limit":1048576}

启动nodeos和keosd容器

docker volume create --name=nodeos-data-volume
docker volume create --name=keosd-data-volume
docker-compose up -d

执行最后一句时会等待很长一段时间,总共16步。。

Creating network "docker_default" with the default driver
Building builder

 。。。。。

遇到如下错误:

CMake Error at src/bsoncxx/CMakeLists.txt:86 (find_package):
  Could not find a configuration file for package "libbson-static-1.0" that
  is compatible with requested version "1.10.0".    

  The following configuration files were considered but not accepted:    

    /usr/local/lib/cmake/libbson-static-1.0/libbson-static-1.0-config.cmake, version: 1.9.3
    

解决方法如下

    short fix is to change the file builder\Dockerfile line 63 to the following:
RUN git clone --depth 1 -b releases/v3.2 https://github.com/mongodb/mongo-cxx-driver \    

the latest stable of mongo-cxx-driver require to update the mongo-driver to be v1.10 and above.

执行完成之后,会启动两个services,nodeosd和keosd。nodeos service将8888和9876端口暴露给主机。keosd不会暴露任何端口,因为它只会被cleos访问,而cleos是运行在keosd容器内部的,详情见下节。

 zexudeMBP:Docker zexu$ docker ps
 CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                            NAMES
 d78d7b5c831a        eosio/eos           "/opt/eosio/bin/keos…"   28 minutes ago      Up 29 minutes                                                        docker_keosd_1
 2478e62b8825        eosio/eos           "/opt/eosio/bin/node…"   28 minutes ago      Up 29 minutes       0.0.0.0:8888->8888/tcp, 0.0.0.0:9876->9876/tcp   docker_nodeosd_1

执行cleos命令

你可以通过一个bash alias来运行cleos 命令。

alias cleos='docker-compose exec keosd /opt/eosio/bin/cleos -u http://nodeosd:8888 --wallet-url http://localhost:8900'
cleos get info
cleos get account inita

上传样品交换合约:

cleos set contract exchange contracts/exchange/

如果接下来你不需要keosd服务了,你可以使用下面的命令来停止服务:

docker-compose stop keosd 

开发/编译个性化合约

因为eosio/eos镜像没有包含合约开发所需要的依赖包(这是by design的,为了镜像容量小的目的),所以需要使用eosio/eos-dev镜像。这个镜像包含了用eosiocpp编译合约所需要的二进制文件和依赖包。

可以使用Docker Hub上的已有镜像或者进入dev文件夹来手动编译镜像。

cd dev
docker build -t eosio/eos-dev .

修改默认配置

可以使用docker compose覆盖文件的方式来修改默认配置。例如:创建要替换的config2.ini文件和一个docker-compose.override.yml,yml文件的内容如下:

version: "2"

services:
nodeos:
volumes:
  - nodeos-data-volume:/opt/eosio/bin/data-dir
  - ./config2.ini:/opt/eosio/bin/data-dir/config.ini

然后重启你的docker容器:

docker-compose down 
docker-compose up

清理data-dir

使用下面的命令清除用docker-compose命令创建的volume:

docker volume rm nodeos-data-volume
docker volume rm keosd-data-volume

Docker hub

Docker Hub镜像可以从Docker Hub上获取到。创建一个新的docker-compose.yaml文件,内容如下:

version: "3"    

services:
  nodeosd:
    image: eosio/eos:latest
    command: /opt/eosio/bin/nodeosd.sh --data-dir /opt/eosio/bin/data-dir -e
    hostname: nodeosd
    ports:
      - 8888:8888
      - 9876:9876
    expose:
      - "8888"
    volumes:
      - nodeos-data-volume:/opt/eosio/bin/data-dir    

  keosd:
    image: eosio/eos:latest
    command: /opt/eosio/bin/keosd --wallet-dir /opt/eosio/bin/data-dir --http-server-address=127.0.0.1:8900
    hostname: keosd
    links:
      - nodeosd
    volumes:
      - keosd-data-volume:/opt/eosio/bin/data-dir    

volumes:
  nodeos-data-volume:
  keosd-data-volume:
  

注意:默认的版本是最新的,可以改成自己需要的

run docker pull eosio/eos:latest
run docker-compose up

EOSIO 1.0 测试网络

可以使用docker镜像可以很容易的在本地创建一个EOSIO 1.0测试网络。运行下面的命令即可:

注意:如果你想使用mogo db插件,你必须在data-dir/config.ini中打开它。

# pull images
docker pull eosio/eos:v1.0.4    

# create volume
docker volume create --name=nodeos-data-volume
docker volume create --name=keosd-data-volume
# start containers
docker-compose -f docker-compose-eosio1.0.yaml up -d
# get chain info
curl http://127.0.0.1:8888/v1/chain/get_info
# get logs
docker-compose logs -f nodeosd
# stop containers
docker-compose -f docker-compose-eosio1.0.yaml down

区块数据默认存储在 --data-dir下面,钱包文件默认存储在 --wallet-dir下面,可以根据需要修改他们。

关于MongoDB 插件

现在mogodb插件在config.ini中是默认关闭的,需要你手动修改这个文件或者在docker-compose文件中将config.ini挂载到/opt/eosio/bin/data-dir/config.ini
